IMPROVEMENT IN PLANlNG-MACHINES.

Specification forming part of Letters Patent No. 165,264., dated July 6,1675; application filed May 1, 1875.

To all whom it may concern:

Be it known that I, JULIAN K. SMITH, of Burrillville, in the county ofProvidence and State of Rhode Island, have invented an Improvement inPlaning-Machines, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a top view, and Fig. 2a side elevation, of my improved machine for matching boards.

Similar letters of reference indicate corresponding parts- My inventionrelates to an improved device for matching boards, to be usedseparately-or in connection with a planer, and to which boards ofanywidth, with parallel or tapering edges, may be fed and matched with asaving of lumber and time.

The invention consists of a swinging and weighted arm, with therevolving matcher at the outer end, moving in an arc-shaped opening inthe bed-plate or table, and adjusting the matcher, by a pivotedguide-piece, to the size of the board.

In the drawing, A represents the bed-frame or table of a planer ormatching-machine, with guide-flange and stationary matcher at one edge,and a swinging arm, B, pivoted at suitable distance therefrom, andcarrying at the outer movable end, in downward extending bearings B, therevolving adjustable matcher O. The bed-plate A is provided with anarcshaped opening, a, andstop-pin b, for the free swinging of matcher O,and the defining of the extent of motion of the same. The matcher isrevolved by a pulley, d, of its shaft, which is connected by beltingwith a revolving pulley, cl, 011 the pivot-pin of the swinging arm B,for the purpose of imparting the regular tension to the belt in everyposition of the cutter.

Arm B is carried, by means of a cord, 0, passing over a pulley, d, andhaving a weight, f, suspended therefrom, toward the end of the openinga, near the outer guide-flange of the bed-plate, and is forced readilysidewis'e, to adjust'the matcher to the board, when the same is fedforward alongthe guide-flange. A guide-strip, E, is applied to thepivot-shaft of the matcher, and swings freely toward the edge of theboard, for guiding it to the cutter, and causing also the uniformworking of the same on the edge of the board, by equalizing, by asmaller depth of cut, any crooks or inequalities in the edge of thesame.

The instant adjustment of the movable cutter to the width and shape ofthe board without any setting of guides produces a greater facility andrapidity in the working of the matchingmachine, and a saving of lumber,time, and labor in matching boards.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the table A, having an arc-shapedslot, a,'pivoted and weighted horizontal arm B, revolving cutter G, andpivotedside guidestrip E, as and for the purpose set forth.
